Status and Trends - Habitat
subbasinYakima Subbasin bar Salmon and steelhead populations are impaired in the Yakima Subbasin due to a number of limiting factors. Primary limiting factors include riparian vegetation, streambed and channel form, and in-channel complexity. Secondary limiting factors affecting fish include altered primary productivity and food competition, altered hydrology, side channel/wetland connection, and water quantity. Since 2008, we have completed a number of projects that have restored stream functions needed to sustain salmon and steelhead in the subbasin.
